(57) [Problem] To provide a novel method for producing a polyaryleneamine having excellent heat resistance. SOLUTION: In the presence of a catalyst comprising a palladium compound and phosphine and a base, the following general formula (1): (Wherein, R 1 to R 5 are each independently a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, a thioalkyl group having 1 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, fluorine, and a carbonyl group. , Carboxyl group, sulfonyl group, sulfoxyl group, Represents a nitro group or a cyano group. Aniline) represented by the following general formula (2): (Where X represents Cl, Br or I, and A represents O, S, S Represents O 2 , CO, CH 2 or C (CH 3 ) 2 . ) Is reacted with an aryl dihalide represented by |
